Also searched as: High Speed Fold-up Door
The High Speed Stacking Door (also called a fold-up or accordion rapid door) is built for large internal and semi-exposed openings where a standard roll-up curtain would be too tall to manage. Instead of rolling, the reinforced PVC curtain folds and stacks vertically on lifting straps, giving a fast, controlled full opening on tall hangar, dispatch and process hall doorways.
Stacking / fold-up doors typically run about 0.6-1.0 m/s (industry synthesis) – a little slower than a slim roll-up because the curtain assembly is heavier, but far faster than a sectional door at the same size. RAX confirms travel speed, strap duty and wind bracing per project rather than publishing a generic figure.
As a pure manufacturer, RAX makes each stacking door to your exact width x height and RAL color – from prototype to container-load delivery order – complete with wiring diagrams and English installation manuals for your local team.
Sources & honesty: RAX-company facts on this page (materials, 100,000-cycle fatigue testing, certifications held, warranty, lead time) are from RAX Door Technology’s approved brand brief. Industry benchmark figures (typical opening speeds, cycle-life ranges, EN 12424 wind classes, ISO 14644-1 cleanroom classes, competitor reference points) are drawn from our sourced category research (research/high-speed-doors.md) and are marked as industry-typical or attributed to the named manufacturer. RAX’s own measured speed, U-value, wind-class certificate and cleanroom class are confirmed per project by test – we do not publish them as generic figures. Fire resistance (EN 1634-1) and ATEX suitability are project-specific capabilities, not blanket certificates.
Vertical fold-up action handles large heights where a rolled curtain would be impractical, keeping a fast full clear opening.
Horizontal bracing bars stiffen the curtain for larger, semi-exposed openings; wind class confirmed per EN 12424 per project.
Servo for precise control and high duty cycle, or VFD for heavier leaves – both manufactured in-house by RAX.
Straps, hinges and drive validated against RAX’s 100,000-cycle fatigue protocol; servo motor carries a 5-year warranty.

| Max opening | Custom to your opening; suited to tall spans – feasible width x height confirmed by our engineers against wind class. |
| Certification | CE EN 13241 / EN 12453 (held); fire (EN 1634-1) and wind (EN 12424) data per project. |
| Order | Custom engineered to your exact opening, specification and RAL color |
Provide clear opening width x height, headroom and side room – or site photos. We produce the confirmation drawing and confirm the feasible span against wind class.
Cycles per day, operating temperature range, wind exposure, and clean / cold / washdown / hazardous-area duty.
Target speed, thermal (U-value), wind (EN 12424), fire (EN 1634-1), acoustic or cleanroom class – we match the applicable standard and confirm by test.
Servo or VFD drive, sensing (radar / geomagnetic / light-curtain), safety edges and any safety-interlock or smart (WiFi/RS485) control needs.
Tall, wide openings where a fast fold-up door beats a slow sectional door without the bulk of a rolled curtain.
Large internal partitions and semi-exposed gable openings in logistics hubs.
High clearances in manufacturing, recycling and bulk-handling buildings.
Where a standard rapid door needs extra curtain bracing to hold its class.
RAX supports full private-label production of the High Speed Stacking Door: custom RAL panel colors, operator matching, packaging printing and installation-manual translation (EN/ES/FR/AR/RU). Start with an OEM sample and scale to container-load branded production. Custom molds, Tooling records are archived for up to 5 years — no extra tooling fee on repeat orders, all under strict NDA.
Product standard for industrial, commercial and garage doors – the harmonized basis for CE marking. Covers mechanical and power-operated safety, wind-pressure and water-penetration resistance, thermal (U-value) and air-permeability performance, with technical documentation retained 10 years.
Safety in use of power-operated doors – operating-force limits and entrapment protection, and the test methods behind our operator safety data.
Wind-load resistance classification (Class 0-5) and the test method for doors. Class 0 denotes no declared wind performance; Class 5 (‘Exceptional’, above 1000 Pa) is set by special maker-buyer agreement.
Any opening size within the High Speed Doors range – large industrial doors from prototype to container-load, full flexibility on order quantity. Share your opening width x height (or site photos) and our engineers confirm the feasible span, wind class and drive sizing, then produce technical drawings.
Stacking / fold-up doors typically open around 0.6-1.0 m/s (industry synthesis) – a touch slower than a slim roll-up because the folding curtain is heavier, but still dramatically faster than a sectional door at the same size. RAX confirms the travel speed and strap duty for your specific opening in the quotation.
Choose a stacking (fold-up) door when the opening is very tall or the curtain must resist more wind – the vertical folding action and bracing bars manage large heights and widths that a rolled curtain cannot. For smaller, sheltered internal passages a standard PVC roll-up door is lighter and a little faster. Share your opening size and exposure and our engineers will recommend the right type.
We are a pure manufacturer and do not provide on-site installation. Every order ships with an English installation manual, wiring diagrams for your local installation team; operators are pre-set and tested before dispatch.
RAX holds ISO 9001:2015 and CE to EN 13241 (industrial door) and EN 12453 (operator safety), with SGS material reports and product liability insurance. Fire resistance (EI60/EI120) and an EN 12424 wind-load class are project-specific capabilities we test and certify per order against the matching standard – we do not overclaim a blanket rating.
Yes. RAL panel colors, operator matching, packaging printing and manual translation (EN/ES/FR/AR/RU) are all supported, from an OEM sample to container-load branded production, under strict NDA.
